What to Do When Your Car Runs Out of Gas?

One option is to go to a gas station to get fuel. Generally, gas stations will provide a fuel can for you, so you don't need to buy one yourself. You just need to pay a deposit, take a taxi back to your car, fill it up, and then return the can. However, getting fuel from a gas station isn't as easy as it used to be. Due to stricter regulations on refined oil, you now need to obtain a permit from the local police station. Moreover, the success rate isn't very high, so this method isn't very practical. Another method that was commonly used in the past is siphoning fuel from a friend's car. All you need is a fuel can and a rubber tube. Insert the tube into the fuel tank, suck on it to start the flow, and then lower the outlet end to let the fuel drain out. Nowadays, even if you're willing to risk drinking gasoline, you might not be able to insert the tube into the tank because many cars have anti-siphoning designs. So, borrowing fuel isn't a reliable option either. You can also call a 4S shop, an insurance company, or a roadside assistance service to deliver fuel to you. However, these companies charge a service fee, which is usually included in the price of the gasoline. It tends to be expensive, so you don't need to order a full tank—just enough to get you to the nearest gas station. This method is feasible but costly. If your car can't move, you can call a tow truck to take it to a gas station. However, towing fees are usually quite high. Alternatively, you could ask a friend to tow your car, but using a rope (soft towing) requires extra caution as it's not very safe.

What are the disadvantages of high oil viscosity?

Lubricating oil with excessive viscosity can lead to the following issues: High viscosity of lubricating oil results in poor fluidity, causing excessively high pressure at the oil pump outlet and an increase in the lubricating oil system pressure. It is advisable to adjust the lubricating oil pump, regulate the oil pressure, or blend in low-viscosity oil. When the oil pressure regulating valve fails, it should be repaired or replaced promptly. Oil may seep into the intake pushrods from the camshaft oil passages and mix into the combustion chamber to be consumed. When the viscosity is too high, the oil circulation rate decreases, leading to reduced cooling effectiveness and the formation of sludge and deposits. High viscosity results in a high friction coefficient, increased engine power loss, reduced output power, and higher fuel consumption.
